Summary:
Now that all our repos are treemanifest, let's enable the extension by
default in tests. Once we're certain no one needs it in production we'll also
make it the default in core Mercurial.
This diff includes a minor fix in treemanifest to be aware of always-enabled
extensions. It won't matter until we actually add treemanifest to the list of
default enabled extensions, but I caught this while testing things.

Summary:
Disable parsing `.hgignore` and related fileset `hgignore()` by default. They can
still be enabled via configuration. The plan is to completely remove them
later.
A replacement for `hgignore()` fileset was added as `gitignore()`.
The `hgignore()` fileset seems to be only used by zertosh in the past 3 months.

Summary:
Add a config option `format.usetreestate`, which would turn on the new
treestate for new repos.
Treestate does not need manually maintaining "copymap", "otherparentset",
"nonnormalset". The one single tree is the source of truth of everything.
So some code like `copymap.pop` etc. are disabled on treestate path.

$TESTDIR is added to the path, so this is superfluous. Also,
inconsistent use of quotes means we might have broken on tests with
paths containing spaces.
To figure out what to do with locally unknown files, Mercurial attempts to read
them if they exist. When an attempt is made to read a file that exists but
traverses a symlink, Mercurial aborts.
With this patch, we first ensure that the file doesn't traverse a symlink
before opening it. This is fine because a file being "remote created" means the
symlink doesn't exist remotely, which means it will be deleted in the apply
phase.
Previously dirstate.walk would return a stat object for files in the dmap
that have a symlink to a directory in their path. Now it will return None
to indicate that they are no longer considered part of the repository. This
currently only affects walks that traverse the entire directory tree (ex:
hg status) and not walks that only list the contents of the dmap (ex: hg diff).
In a situation like this:
mkdir foo && touch foo/a && hg commit -Am "a"
mv foo bar
ln -s bar foo
'hg status' will now show '! foo/a', whereas before it incorrectly considered
'foo/a' to be unchanged.
In addition to making 'hg status' report the correct information, this will
allow callers to dirstate.walk to not have to detect symlinks themselves,
which can be very expensive.
Many tests didn't change back from subdirectories at the end of the tests ...
and they don't have to. The missing 'cd ..' could always be added when another
test case is added to the test file.
This change do that tests (99.5%) consistently end up in $TESTDIR where they
started, thus making it simpler to extend them or move them around.
